What can we do if the Optoma EP727 will not start after replacing the projector lamp so that it starts well with the old projector lamp?
Question from customers
Question from Marc L.
The lamp of my Optoma EP727 has reached its end of life. I replaced it with a new lamp, my Optoma EP727 starts as usual but after a few hours, everything is turned off, there is no more than red light. I tried again to turn it on in several times but in vain. When I tried it with the old lamp everything worked fine but only a few seconds, which I think normal because it is already out of service.
I would like to ask you if you know the problem. Does a cleaning is required and at what level?
Thank you in advance for the answer.

To begin, it is necessary to isolate the failure to know if the problem was the Optoma projector lamp, ballast and other things. It is therefore necessary to shunt the detection lamp and then check if your projector works well with a light source before putting in any new lamp projector for your Optoma EP727. In cases like this, the ballast is often out of service.
You can also think of cleaning air filters and check if the fans are not disconnected, if they are in good working.
